(Cl. 18S-'75) Claims.

This invention relates to Window constructions, particularly adaptable for railway cars, buses, and other vehicles, and has for its object a window construction wherein the sash is attached in the window frame or window opening by a clamping action and by clamping means located in the window opening, so that there are no screw heads exposed on any exposed surface of the sash.

It further has for its object a construction by which the sash equipment including the sash and the means for securing the sash in the window opening may be applied, as a unit, by the car builder, and the sash, and particularly the securing or clamping means applied by the car builder to the window openings or frames without special construction of window frames to accommodate the securing means.

It further has for its object a construction by which a double sash, that is, a sash with two spaced apart glass panes, may be permanently attached in a window frame opening by the equipment supplied to the car builder and the glass panes readily removed and replaced Without demounting the sash, and hence without fastening means which are exposed.

It will be understood that fastening members, as screws, which are exposed, particularly on the outer surface of the car, regardless of how carefully the heads of the screwsare concealed, collect soot and dirt forming rings around the heads of the screws, and lines in the slots of the screw heads, if slotted screws are used, so that the fastening members are more conspicuous, regardless of how much care is taken to provide smooth surfaces to conceal them, than if no attempt were made to conceal them.

It further has for its object fastening means including base plates which are readily attached to the window frame and clamping members, which are readily applied to the sash and to the base plates, after the base plates have been attached to the window frame and the sash has been placed in position for linal tightening or clamping.

I designates, generally, the window frame which confines the Window opening 2, this being part of lthe sheet metal structure of the car body. 3 designates the sash, this being formed of metal, usually by an extruding process, and the sash is formed with a flange 4 on the outer side thereof which laps at 5 the outer face of the window g frame or car body around the window opening. This flange is usually one side of a peripheral channel 6 formed in the edge of the sash. The opposite or inner side of the channel is a flange 'I of less width than the flange 4 and arranged with its edge 8 spaced apart from the window frame providing a space at 9 for the clamping means. The sash is intended to be permanently mounted in the car body and is constructed to sup-port glazing means or strips, which permit the removal and replacemena'when necessary,

` of the glass pane or double glass panes', as III, I I

The invention consists in the novel features and in the constructions and combinations hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the Views.

Figure 1 is a fragmentary elevation of a Window structure embodying this invention, the inwithout demounting the sash.

As here shown, the glazing means includes an intermediate strip I2 of resilient compressible material, as rubber, extending between the margins of the glass panes Ill, II and also extending into a channel I3 in the sash, and removable glazing strips I4, I5 of similar material having head portions pressing against the outer margins of the glass panes II), II respectively, and base portions extending into grooves or channels in the sash. These glazing strips I4, I5 are generally removable and replaceable and so constructed as not to crawl or work` out of the grooves in which they are located. The specic construction of the glazing means forms no part of this invention.

The means for securing the sash to the window frame comprises base plates, which lie flatwise on the window frame within the window opening and which are attachable to the window frame, and clamping members coacting with the base plates and with the sash and placeable in coacting relation with the base plates andwith the sash, after the base plates'have been` applied to the window frame and the sash has been placed'in the window opening preliminarily to `being tightened in position by clamping the Y and thewindow frame, and isformed with an in- Wardly extending ange or lug il Ato which the clamping member is attached. In order that'the base plates may be readily attached to the window frame, each is preferably vformed with a stem lhaving an angular Yshoulder or lug I9,

modating the curtain roll and because of the curtain roll itself, it is impractical to provide the fastening members, including the base plates. Therefore, a diiferent form of clampingmeans is provided along the top rail of the sash for clamping the flange d against the windowirame. As here shown, the clamping means along the top rail include clainpincr screws 32v extending through the narrow flange l ofthe channel 6 and thrusting at their inner ends-against the flange or wall 33 of the chamber 34 in which the curtain roller is located. Each screwV 32 threads through a nut 35 thrusting against the inner face of the flange l. rlhis nut is square, so as to be held from turning with thescrew,

.by reason of the fact that one sideV thereof lies iiatwise on the bottom of the channel The the base plate `being attached to the window frame by moving it to insert the stem i8 throughY adrlled hole 20 in the Window frame, and then shifting it laterally to interlock the shoulder or lugIIS/under the margin of therwall 'around' the hole, the angular shoulder or lug I9 being so located that Ythe'thrust of the'clamping member on'the base plate causes the lug to hookV under the'margin of. thewallt around the opening 26. 2li' designateslthe clamping membersl Each clamping member'includes a threaded shank 22 andanfangular'heacl'portion 23.. The shank extends vthrough a'slot 22l`in the flange il, which flange is located outside of the sash of the channel S'on the inner side o'f the sash and the head 23coacts.with the inneriace of the shorter side of the flange 'l of the-channels; the shank vex'- tending through the space 9. `Annut 25 threads onthe shank 22 against theflangeli. The slot 24inthe1ilange I'! opens at 25 through a lateral edgeof the'ange I1.' r Y The sash and the 'clampingjmembers are supplied rto the car builder, and in applying the sash equipment to thelwindowopening, the car builder boresthe holes 2D at suitableintervals in the Windowframe, and places the baseplates in position.` He then places the sash in the window opening with the flange 4Y or Vportion S'thereof opposed to Athe outer side of the window frame.

T-he clamping members are thenV manipulatedl through the space 9 to bring the'head's23 thereof on'the inner side of the flange 7. Then the clamping members are slid laterally to bring their shanks-into'the slots 26-ofthe flanges-I7 of the base plates. The nuts 25 are thentightened, thus Vclamping the flange 4 against Ythe'window frame and firmly clampingY the sash tightly in position;

The flanges l1, shanks-ZZ and nuts 25 are yconcealed` by the interior trim of the car. Along the 'lower side ofthe sash, 'this interior trim isy a hollow sheet metal sill 2'! secured to the window frame, as byscrews 2B. Along theyertical sides of. the sash, interior trim strips 29, similar to the/sill, are provided and` held in position'byscrews .30, these strips 2S being formed with the usualcurtainguide .31. The screws 2S-and 3i! arethe `type Vof screw which bore andftap the "f holes, and in Figure 6, the'base plates are shown as secured to the. window frame by-similar screws I8a .instead-of by. the stem I8 with' theangular shoulders or. lugs I9. f

The Vframe along the upper rail of thesash is diiferentfroin *portions constituting the bottom andvertical sides of. thewindow opening becauseY usuallyy the curtain-.rolls are housedin the window frame above the top rail ciA the sash. Because ofjthedepth of 'this recess orchamberfor accomheads 36 of thee-crews are here shown as square.

When thecurtain is applied, the heads of the screws are concealed by the curtain, by the wall of' the chamber andthe interior trim 3l. The

clamping mea-ns consisting of the's'crews 372 and nuts y5'V are thus self-contained with the sash.

In Figure-5a modified form of clamping means is shown in which the base 38, correspondingto the base iii-0f Figure 3 is arranged with its'angu- Y lar flange or lug 3Q located inthe channel of the sash instead of Vout of ,the channehasrin Figure 5, and the clamping members are screws lill extending through holes inthe narrow flange 7 and threading through av nut il on side of the narrow flange 7,the screw to the inner face of the narrow ange l and then the screw dit tightened. Intightening the screw, theinner end thereof thrusts against the lug or flange 39 causing the nut 4i to react against the flange l, and hence draw the sash Y2 and clamp the iiange 4 tightly against the outer face of the window frame..

By this construction, the car manufacturer can readily apply the sash equipment consisting ofv the sash and its vsecuring means to a window.
